Measurements of diurnal variations and eddy covariance (EC) fluxes of glyoxal in the tropical marine boundary layer: description of the Fast LED-CE-DOAS instrument [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
Here we present first eddy covariance (EC) measurements of fluxes of glyoxal, the smallest α-dicarbonyl product of hydrocarbon oxidation, and a precursor for secondary organic aerosol (SOA).

Glyoxal vertical columns from GOME-2 backscattered light measurements and comparisons with a global model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Glyoxal vertical column densities have been retrieved from nadir backscattered radiances measured from 2007 to 2009 by the spaceborne GOME-2/METOP-A sensor.

Data_Sheet_1_Nanogold sol plasmon discattering assay for trace carbendazim in tea coupled aptamer with Au3+-glyoxal-carbon dot nanocatalytic reaction.docx

open access: yes, 2023
Carbendazim (CBZ) is a broad-spectrum fungicide, which is toxic to mammals. Therefore, it is very necessary to establish a sensitive detection for food safety. An experiment found that CDFe exhibited excellent catalysis for the nano-indicator reaction of

Glyoxal damages human aortic endothelial cells by perturbing the glutathione, mitochondrial membrane potential, and mitogen-activated protein kinase pathways

open access: yesBMC Cardiovascular Disorders, 2021
Background Exposure to glyoxal, the smallest dialdehyde, is associated with several diseases; humans are routinely exposed to glyoxal because of its ubiquitous presence in foods and the environment.

Revisiting the global budget of atmospheric glyoxal: updates on terrestrial and marine precursor emissions, chemistry, and impacts on atmospheric oxidation capacity [PDF]

open access: yesAtmospheric Chemistry and Physics
Atmospheric glyoxal (CHOCHO) plays critical yet incompletely understood roles in tropospheric chemistry. Current models substantially underestimate glyoxal abundance over both land and ocean, indicating knowledge gaps in our understanding of its sources ...

Simulation of semi-explicit mechanisms of SOA formation from glyoxal in aerosol in a 3-D model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
New pathways to form secondary organic aerosol (SOA) have been postulated recently. Glyoxal, the smallest dicarbonyl, is one of the proposed precursors.

Chamber studies of SOA formation from aromatic hydrocarbons: observation of limited glyoxal uptake [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
This study evaluates the significance of glyoxal acting as an intermediate species leading to secondary organic aerosol (SOA) formation from aromatic hydrocarbon photooxidation under humid conditions. Rapid SOA formation from glyoxal uptake onto aqueous (

Glyoxal in hyperglycaemic ischemic stroke – a cohort study

open access: yesCardiovascular Diabetology, 2023
Background Hyperglycaemia is frequent in acute ischemic stroke and denotes a bad prognosis, even in the absence of pre-existing diabetes. However, in clinical trials treatment of elevated glucose levels with insulin did not improve stroke outcome ...

A Retrieval of Glyoxal from OMI over China: Investigation of the Effects of Tropospheric NO2

open access: yesRemote Sensing, 2019
East China is the ‘hotspot’ of glyoxal (CHOCHO), especially over the Pearl River Delta (PRD) region, where glyoxal is yielded from the oxidation of aromatics.
